  Log:
  MFC:
  
  The resource_xxx routines in subr_hints.c are called before and after the
  kenv environment in kern_environment.c switches to dynamic kenv. The prior
  call sets the static variable hintp to the static hints in subr_hints.c
  (hintmode==0).
  
  However, changes to the environment are not detected by the resource_xxx
  lookups after the change to dynamic kernel environment, so the lookup
  routines only report the old stuff of hintmode==0, even after the change to
  the dynamic kenv. This causes kenv users to see a different environment than
  the kernel routines.
  
  This is a problem in the mixer.c code that looks up initial mixer volume
  settings from the hints: If the hints are dynamic and not from the
  device.hints file, mixer.c doesn't see them, but kenv does.
  
  The patch from the PR (modified to comply to the style of the function)
  solves this.
